Answer:
58°
Step-by-step explanation:
65°+57°=122°
180°-122°=58°
Each oil change ( x ) takes 22 minutes which can be represented as 22x.
Each tire rotation ( y ) takes 18 minutes, can be represented as 18y
Now, we have only 5500 minutes available, therefore the sum of both things can not last more than this time.
The inequality represented is:
Answer:
The final estimate of √388 is 20.
Step-by-step explanation:
The number provided is:
<em>x</em> = 1388
Estimate the square root of 1388 as follows:
15² = 225
16² = 256
17² = 289
18² = 324
19² = 361
20² = 400
So, we now know that the square root of 388 lies between 19 and 20.
Check for 19.5²:
19.5² = 380.25
Check for 19.6²:
19.6² = 384.16
Check for 19.7²:
19.7² = 388.09 ≈ 388
The square root of 388 is closer to 19.7 or is approximately 20.
Thus, the final estimate of √388 is 20.
